In this manuscript, the synthesis and biological activity of a series of pyrazole acetic acid derivatives as CRTh2 antagonists is presented. Biological evaluation in vitro revealed that the pyrazole core showed in several cases a different structure-activity relationship (SAR) to that of related indole acetic acid. A potent series of ortho-sulfonyl benzyl substituents was found, from which compounds 27 and 63 were advanced to in vivo profiling.
Formation of functionalized 2H-azirines through phio-mediated trifluoroethoxylation and azirination of enamines

A variety of enaminones and enamine carboxylic esters were converted to trifluoroethoxylated 2H-azirines through reactions with PhIO in trifluoroethanol (TFE). The cascade reaction is postulated to proceed via a PhIO-mediated oxidative trifluoroethoxylation and a subsequent azirination of the α-trifluoroethoxylated enamine intermediates.
